Garmin Descent G1

The Garmin Descent G1 is a rugged dive computer and GPS smartwatch designed for both underwater and land-based activities. It features six dive modes, customizable dive alerts, advanced fitness tracking, and long battery life (up to 25 hours in dive mode and 21 days in smartwatch mode), making it an ideal companion for divers and adventurers alike.

About Garmin Descent G1

The Garmin Descent G1 is a versatile dive computer and GPS smartwatch that combines advanced diving functionality with comprehensive fitness tracking features. Designed for both underwater and land-based activities, this rugged device offers a high-contrast monochrome display, multiple dive modes, and a battery life of up to 25 hours in dive mode or 3 weeks in smartwatch mode.

Adapt to Any Dive Style with Six Specialized Modes

The Garmin Descent G1 offers six dive modes to match different diving styles and preferences. These modes provide tailored features for various underwater activities:

  • Single-Gas & Multi-Gas Modes: Support up to 12 gas mixes with oxygen content ranging from 5% to 100%.
  • CCR (Closed-Circuit Rebreather) Mode: Allows for two partial pressure of oxygen (PO2) setpoints and supports both closed-circuit and open-circuit gases.
  • Gauge Mode: Provides essential bottom timer features.
  • Apnea & Apnea Hunt Modes: Designed for freediving, with Apnea Hunt mode specifically optimized for spearfishing.

The device enables divers to set up multiple breathing gases, including oxygen and helium percentages, ensuring accurate decompression calculations. For precise dive predictions, only gases that will be used should be enabled.

Stay Powered Longer with Extended Battery Life

The Garmin Descent G1 offers impressive battery life across different activity modes, allowing for extended use in various conditions:

  • Dive Mode: Up to 25 hours of use.
  • Smartwatch Mode: Lasts up to 21 days, or up to 124 days with solar charging (G1 Solar model).
  • GPS Mode: Provides 26 hours of battery life, extending to 39 hours with solar charging.

Factors like GPS usage, backlight settings, and enabled sensors may impact battery life. Dive activities consume more power, typically draining 5-10% per 1-1.5 hour dive. To maximize battery efficiency, divers can adjust power modes, disable unnecessary features, and take advantage of solar charging for extended performance.

Enhance Safety with Customizable Dive Alerts

The Garmin Descent G1 provides a range of customizable dive alerts to improve safety and awareness during underwater activities. Divers can personalize alerts for key parameters:

  • Depth Alerts: Triggered upon reaching a specified depth.
  • Time Alerts: Activate after a set time interval.
  • Speed Alerts: Notify divers of vertical ascent or descent rates.
  • Pop-up Notifications & Vibration: Customizable alert options for added awareness.
  • Mode-Specific Alerts: Includes neutral buoyancy alerts for apnea diving.

These alerts can be configured through the watch’s menu system or the Garmin Connect app, allowing for a personalized and safe diving experience.

I just bought this as my

I just bought this as my first dive computer- used it on a recent trip for 4 dives. It was great! Easy to use, worked as expected, and was very excited to be able to have my own gear for managing the dive, like safety stop time and keeping track of my depth. My friend who’s a tech diver liked it so much she’s going to get it for herself too- so it’s good regardless of your level! Plus the price point makes it an achievable investment.

The watch does its job well.

The watch does its job well. Have yet to see it in action on a dive, but for everything else, my wife seems very happy with it and wears it every day. The color is nice too. Battery lasts a very long time.

I was deciding between dive computers

I was deciding between dive computers and I’m extremely satisfied and happy I chose this one! I’ve used it on multiple dives and also night dives and it’s very user friendly, accurate, and the display is clear to see even on night dives with the backlit display. It’s also an awesome sports watch, I use it everyday for all my activities. And the battery life is AMAZING, lasts for daysss even when diving constantly!
